Over 1,200 electric cars involved in V2G project in China
As reported by the state news agency Xinhua, these electric cars charge during off-peak times and make electricity available to the grid again in the event of impending bottlenecks. According to the grid operator State Grid Jiangsu Electric Power, participants were recruited for the project through discount vouchers, meaning that 1,277 electric vehicles at 482 charging stations are now involved in the project.
An employee of the grid operator is quoted by Xinhua as saying that the number of electric vehicles in Jiangsu is expected to exceed 10 million units by 2030. “If just 10 per cent of these vehicles participate in reverse discharging, they could provide over 1 million kilowatts of peak-shaving capacity, equivalent to plugging in a 1 million-kilowatt ‘portable power bank’ to the grid.”
State Grid Jiangsu Electric Power is also currently conducting a V2G test with electric buses. However, only two vehicles are involved in this case. “Compared to ordinary new energy vehicles, buses offer advantages such as larger single-charge discharge capacity, stable charging times, and scalability, providing a novel technological approach to green transportation, clean energy consumption, and power supply security in the region,” said Jiang Renxin, Director of the Marketing Department of State Grid Zhenjiang Yangzhong Power Supply Company.
